Receptors uas kho cov lus teb rau cov neurotransmitter acetylcholine yog nicotinic thiab muscarinic.

Yuav ua li cas receptors teb rau acetylcholine?

Acetylcholine receptors (AchRs) raug cais los ntawm lawv lub peev xwm los teb rau ob leeg muscarine (M₁-M ₅) los yog nicotine (nAchR) Muscarinic receptors yog classic G protein-coupled receptors (GPCRs), ua ke rau G_{i, uas inhibits cAMP ntau lawm. Nicotinic AchRs yog ligand-gated voltage channels.}

Dab tsi receptors khi rau thiab teb rau acetylcholine?

Acetylcholine hauv ANS

ACh khi rau muscarinic receptors (M2) uas pom muaj nyob hauv cov hlwb suav nrog cov sinoatrial (SA) thiab atrioventricular (AV) nodes. Muscarinic receptors yog txuas rau G_{i-protein; yog li ntawd, vagal activation txo cAMP.}

Cov receptors rau acetylcholine nyob qhov twg?

Acetylcholine receptors muaj nyob rau ntawm saum npoo ntawm cov leeg nqaij, concentrated hauv synapse ntawm paj hlwb thiab cov leeg hlwb.

Tus receptor zoo li cas yog acetylcholine receptor?

Tus nicotinic acetylcholine receptor yog ib qho piv txwv ntawm a ligand-gated ion channel. Nws yog tsim los ntawm tsib subunits teem symmetrically nyob ib ncig ntawm ib tug central conducting pore.
